Abstract
(EN) The present disclosure provides an operation method of a first terminal in a wireless communication system, and an apparatus for supporting same. An embodiment applicable to the present disclosure may comprise the steps in which: the first terminal performs a beam alignment with a second terminal; and the first terminal receives downlink control information (DCI) related to the second terminal from the base station. The DCI may be decoded on the basis of at least one of a common radio network temporary identifier (RNTI), a sidelink-RNTI (SL-RNTI) of the second terminal, and a sidelink connection specific ID. Furthermore, the embodiment may comprise a step in which the first terminal receives a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH) from the second terminal on the basis of the DCI.
(FR) La présente invention concerne un procédé de fonctionnement d'un premier terminal dans un système de communication sans fil, et un appareil pour le supporter. Un mode de réalisation applicable à la présente invention peut comprendre les étapes dans lesquelles : le premier terminal effectue un alignement de faisceau avec un second terminal ; et le premier terminal reçoit des informations de commande de liaison descendante (DCI) relatives au second terminal depuis la station de base. Les DCI peuvent être décodés sur la base d'au moins l'un des éléments suivants : un identificateur temporaire de réseau radio commun (RNTI), un RNTI de liaison latérale (SL-RNTI) du second terminal et un identificateur spécifique de connexion de liaison latérale. En outre, le mode de réalisation peut comprendre une étape dans laquelle le premier terminal reçoit un canal de commande de liaison latérale physique (PSCCH) et un canal partagé de liaison latérale physique (PSSCH) du second terminal sur la base des DCI.
(KO) 본 개시는 무선 통신 시스템에서 제1 단말의 동작 방법 및 이를 지원하는 장치를 개시한다. 본 개시에 적용 가능한 일 실시 예에 따르면, 상기 제1 단말이 제2 단말과 빔 정렬(beam alignment)를 수행하는 단계 및 상기 제1 단말이 기지국으로부터 상기 제2 단말과 관련된 DCI(downlink control information)를 수신하는 단계를 포함할 수 있다. 여기서, 상기 DCI는 공통 RNTI(common radio network temporary identifier), 상기 제2 단말의 사이드링크-RNTI(SL-RNTI) 및 사이드링크 연결 특정 아이디(sidelink connection specific ID) 중 적어도 하나에 기초하여 디코딩될 수 있다. 또한, 상기 제1 단말이 상기 DCI에 기초하여 상기 제2 단말로부터 PSCCH(physical sidelink control channel) 및 PSSCH(physical sidelink shared channel)를 수신하는 단계를 포함할 수 있다.
